I have been searching for a couple of weeks for the dimensions to a Capcom showcase cabinet like this one:

Capcom made several variations of this design, where the marquee is in a separate box above the main cab, and the speakers are where the marquee is usually located on most upright designs. This cab was used by Capcom for several CPS2 and CPS3 games. I have never seen anyone built this type of cab nor can I find the dimensions on line. Can someone help me?
I plan on building this type of machine housing a computer and a supergun.
I will document the build stage and have available design dimensions for all variations of Capcom cabinets, post-Street Fighter II (Street Fighter II cabs are well documented).
Thanks, Tornado-Claw
